Instructors in 14 Navy electronics A schools 12 basic core and 2 advanced were presented with a list of 70 mathematical skills and asked to indicate 1 how important they were to successful school performance and 2 whether they were prerequisite, reviewed, or taught in the A schools. Also, they were asked to state the number and type of performance aids used in the course and during the exam. Responses showed that, of the 70 skills surveyed, 19 do not appear in any basic core course and 2 more do not affect performance. Although the skills rated as affecting performance are generally considered as prerequisite in all schools, many students require review in these skills for successful performance. Across all schools, the most important skills are 1 addition, subtraction, multiplication, and division of numbers, 2 squares and square roots of positive numbers, 3 addition and subtraction of like units, 4 multiplication and division of like andor unlike units, 5 substitution of known values into a given formula, and 6 transpositions of algebraic expressions. Performance aids are permitted in all courses but one, both during the course and during exams.
